DAYTON, Ohio — Officials say a more than $40 million expansion of the National Museum of the U.S.Air Force in southwestern Ohio will open in June.
The privately financed 224,000-square-foot hangar at the aviation museum near Dayton is scheduled to open June 8. Officials say the building is expected to draw more visitors to the museum that attracts more than a million people a year.
Curators began moving historic and experimental aircraft into the new hangar this past fall. Those aircraft include the delta-winged XB-70 Valkyrie supersonic bomber, the hypersonic X-15 rocket plane and the YF-23 Black Widow II advanced tactical fighter.
About 52 aircraft have been towed into the hangar so far. Around 70 aircraft, missiles and space artifacts will be on display in four galleries when the expansion is completed.
